A fuel nozzle assembly for dispensing fuel from a source to a container includes a body defining a fuel flow path and a vapor recovery path. The nozzle includes a venturi valve in the fuel flow path which defines a venturi port and a diaphragm valve positioned in the vapor recover path, The diaphragm valve has a control section having a control port which is in fluid communication with the venturi. The diaphragm valve is normally spring biased closed. When gas flows through the venturi and over the venturi port, it creates a vacuum in the diaphragm control section sufficiently strong to open the diaphragm valve so that recovered vapors may be returned to a source of fuel, or other collection area, such as an underground storage fuel tank.
